“Like a sailor crossing the ocean guided by the sky’s dome, I found my star, the astronomical sky,” says Jacob & Co Like Man founder Jacobarabo Since ancient times, Jacob & Co. has been fascinated by observing the night sky and is inspired by the countryside Inspired by astronomical clocks, technical and aesthetic masterpieces, this new technique was completed.

In 2014, the Astronomia three-axis gravity tourbillon watch launched by Jacob & Co. has amazed the watch industry. This year, the brand takes this challenge further with the Astronomia Sky watch, adding a new complication: a three-dimensional star display that combines celestial indicators and day/night information. In order to understand the full complexity of this feat, each innovation will be individually detailed.

sidereal time
The celestial disk covering the base of the Astronomia Sky case completes one rotation in one sidereal year, the time it takes for the Earth to orbit the Sun relative to the stars. The celestial dial is made of grade 5 blue titanium and features 18-karat gold stars and hand-engraved zodiac signs. best replica watches
celestial indicator

Above the star dial, an elliptical celestial indicator shows the portion of the star visible from the northern hemisphere. The dial completes one revolution in one sidereal day, the time it takes for the Earth to rotate once on its axis (23.560916 hours).
day/night indicator

At the center of the satellite axis, a hand-carved lacquered titanium sphere rotates on its own, shaded by a tinted sapphire crystal dome symbolizing day and night. The Earth rotates synchronously with its satellites, completing a rotation every 20 minutes.

The race for satellites
4 satellites rotate around the dial in 20 minutes. Among them, the three-axis gravity tourbillon completes one revolution every 60 seconds on the first axis, one revolution on the second axis every 5 minutes, and one revolution around the dial every 20 minutes. https://www.moon-watch.co

The hour and minute indications can always be read in the correct orientation thanks to an ingenious differential system, with the indexes remaining vertical.
The third satellite is the orbiting seconds indicator, a skeletonized titanium wheel that rotates on itself every 60 seconds and around the dial every 20 minutes.

Finally, the fourth and final moon is a “Jacob cut” orange sapphire with 288 facets. The first sapphire in contemporary jewelry, this sapphire rotates around its axis every 60 seconds and around the dial every 20 minutes.

Optimization and adjustment
Jacob & Co. sought a solution that would adapt this major complication in the simplest possible way. The Astronomia Sky has two handles and two wheels on the bottom. The first knob allows setting the time and day/night indicator, both based on the 24-hour solar rhythm. The second handle is used to operate the mechanical movement. As for the wheels, the first allows you to adjust the sidereal hours and the other allows you to adjust the celestial indicators.
Jacob & Co. is known for its unique and bold complications, and its Astronomia Sky watch once again proves its talent. wholesale replica watch

Breitling Navitimer B02 Chronograph 41 Cosmonaute: The First Swiss Watch In Space Returns

zelin0802

The Breitling Navitimer B02 Chronograph 41 Cosmonaute Limited Edition celebrates the manufacturer’s connection to spaceflight. Today, Breitling is celebrating the 60th anniversary of the Mercury Atlas 7 mission, during which astronaut Scott Carpenter wore a special Navitimer on his wrist as he circled the Earth three times. In fact, since May 24, 1962, Breitling has officially won the title of “the first Swiss space watch”. Carpenter’s watches are modified aviation chronographs that offer a 24-hour display, allowing astronauts to distinguish between day and night. Now Breitling has launched a modern update, limited to 362 pieces. At the same time, the brand also launched the Astronaut’s original Cosmonaute and presented the severely damaged watch to a selected audience.

With this special edition, Breitling hopes to highlight the link between Swiss watchmaking and the conquest of space. However, the watch is also attacking Omega’s dominance in the subject area, which is no problem for Breitling CEO George Kern. He said: “We’re not going to attack anyone. […] We’re only doing this because this watch is so historically significant: it was and remains the first Swiss watch to go into space.

The case is (almost) similar to the original
The case of the fake Breitling Navitimer B02 Chronograph 41 Cosmonaute Limited Edition remains faithful to the prototype. The body is stainless steel, but Breitling outfitted this special edition with a platinum bezel. This is also the most obvious difference from the original Cosmonaute. The new bezel features a grooved design for improved maneuverability. The watch measures 41mm in diameter, 13mm in height and features satin and polished surfaces.

On the side are the chronograph pushers and crown. The latter is not screwed, which is why the watch is only guaranteed to be water resistant to 3 bar or 30 meters. There is a window on the back of the case to view the mechanism. Around the crystal, Breitling also engraved Carpenter’s mission date, a limited edition of 362 pieces, and the words “the first Swiss watch into space”.

Dial with 24-hour display
The dial has a 24-hour display that distinguishes between day and night. Arabic numerals with rectangular hour markers, all with vintage Super-LumiNova. The white main hands are also illuminated, so they are clearly legible even in the dark.

The dial is surrounded by a tachymeter scale, which, along with a white slide rule, can be used for simple calculations. As an aviation chronograph, the wing logo of the Aircraft Owners and Pilots Association (AOPA) appears on the dial at 12 o’clock. Last but not least, there is a small seconds hand at 9 o’clock, while the totalizers are located at 3 and 6 o’clock. A date window is also included with its black numerals integrated into the 12-hour counter at 6 o’clock.

Homemade chronograph movement B02
Inside is the buy cheap watch is a B02 manufacture movement with manual winding. In the version used here, the hour hand completes only one revolution per day instead of two to enable the 24-hour display. The movement has a power reserve of 70 hours and operates at 4 Hz.

It also integrates a chronograph that uses a column wheel. At the same time, the vertical clutch ensures that the needle starts smoothly. The COSC certificate, which guarantees the corresponding accuracy, also demonstrates the performance of the mechanism. On this watch, the movement has many decorations that allude to the Mercury 7 mission. In addition, Carpenter’s name is engraved on the metal.

The Breitling Navitimer B02 Chronograph 41 Cosmonaute Limited Edition comes with a seven-row Navitimer stainless steel bracelet. Alternatively, there is a black alligator strap with a folding clasp.
